I agree, which is why I would prioritize the other fixes as well. Still, these kinds of things (once broadly learned by the community) can have a significant impact.

Yes, it won't be 100%, but it would reduce the conversion rate of the scammers. That's ultimately the solution. No single measure will ever fix this, and if you wait to implement something until you will solve the entire problem space you'll never get started.

The solution is a hundred different changes that each reduce the scammers' conversion rate by 1-2%.
